Job description

About Us

Asteri is an AI-native Work Intelligence and Orchestration Platform that gives large enterprises the intelligence to understand how work is performed today and how it should be performed in the era of AI, eliminating inefficiencies and identifying high-impact opportunities for AI augmentation. Our platform orchestrates AI and human work with enterprise-grade governance, auditability, and measurement built for production environments at scale.

The Role

As a Frontend Engineer at Asteri, you’ll lead the evolution of our user interfaces and front-end architecture. You will build the interactive platform that powers our AI-native orchestration engine, ensuring that complex data workflows and AI-driven insights are delivered through intuitive, high-performance web applications. While your primary focus is the presentation layer and front-end architecture, you will work closely with backend systems, understanding the full lifecycle of data from the database through the API to the user.

What You’ll Do

• Build sophisticated, high-performance front-end systems using modern frameworks (e.g., Next.js, React).




• Create rich, intuitive TypeScript interfaces that provide visibility into orchestration workflows, AI performance, and operational insights.




• Collaborate closely with designers and product managers to translate complex AI orchestration concepts into seamless user experiences.




• Bridge the gap between front and back: Design and consume clean, well-documented APIs (FastAPI, Node.js) while ensuring type safety and efficient data fetching across the stack.




• Optimize front-end performance and scalability, ensuring a responsive experience even when handling large datasets and real-time updates.




• Integrate with internal and external APIs (e.g., Jira, Slack, document stores) to create a unified orchestration graph within the UI.




• Ensure production reliability on the front end: Implement comprehensive testing (Unit, Integration, E2E), CI/CD pipelines, and monitoring.




• Champion front-end engineering excellence: Drive architectural decisions, establish best practices, and mentor peers in modern UI development

What Will Make You Successful

Must-Haves

• 5+ years of software engineering experience, with a deep focus on front-end development and architecture.




• Mastery of TypeScript and modern React patterns (Hooks, Context, Server Components, etc.).




• Strong understanding of the full web stack: Experience working with APIs (REST, GraphQL) and an understanding of database concepts (Postgres, SQL).




• Proficiency with CSS/styling frameworks (Tailwind, CSS-in-JS) and a keen eye for UI/UX detail.




• Experience building and deploying production-grade web applications using containerized workflows (Docker).




• Strong engineering rigor: testing (Jest, React Testing Library, Playwright/Cypress), peer review, and CI/CD.




• Excellent communication and collaboration skills; ability to lead front-end initiatives from concept to production.

Nice-to-Haves

• Experience with state management libraries and data-fetching strategies (React Query, SWR, Redux).




• Familiarity with LLMs and building AI-driven user interfaces (streaming responses, prompt-based interactions).




• Exposure to back-end development with Python (FastAPI) or Node.js.




• Knowledge of data visualization libraries (D3.js, Recharts, etc.) for displaying complex orchestration graphs.




• Familiarity with high-growth startups and/or agile, fast-moving environments.




• Interest in building developer tools or productivity platforms.

Why Join Us

You’ll shape the frontend of an AI-native work intelligence and orchestration platform used by large enterprises, building interfaces that make complex systems understandable, trustworthy, and usable. You’ll work closely with Product, Design, and Backend teams to define frontend architecture and standards, with real ownership over performance, quality, and user experience. We offer competitive compensation with equity, a remote-friendly culture, and a pragmatic, production-first approach to building enterprise AI software.
